MILAN, Italy, April 18 (UPI) -- Work has begun on restoring Milan's tallest building, damaged when a small plane crashed into it two years ago, the Italian news agency ANSA reports.
On April 19, 2002, a small plane ploughed into the Pirelli Building's 26th floor killing three people and injuring several others.
The crash set off an international alarm because it was thought to be the work of terrorists. After several anxious hours the Italian authorities said it was an accident.
According to police reports at the time, the plane developed a fault and burst into flames shortly after taking off, and the Swiss pilot apparently lost control of aircraft. The pilot -- the plane's sole occupant -- and two office workers were killed.
The Pirelli Building, one of the city's best known landmarks, was designed by leading Italian architects Gio Ponti and Pier Luigi Nervi as the headquarters of the Italian tire corporation, but now houses government and city offices.
